Hi, i am not quite sure about what is your question :wtf: so i can not answer

For a sample, it has to be the sensor that works on same principal as stock one, you have to find linearisation from the car that the new sensor "come from", you have to alter your sensor linearisation axis and values, sometimes also some another maps and you have to check te circuit for both of sensors that you can pair the wires...

I newer touch the wiring on the car, i make adapter so i can plug it in...like on the photo.

NIce work. I might need to extend my MAF sensor cable so might do as you did with the extension cable.

Did you find the t-map temp linearisation maps ?

I struggled to get my head around the data.
My ECU uses 1023 as 5v.
Looking at the temp vs resistance values...and the fact they say use a 1k ohm series resistor...
..I found out how the tables work in my ECU.
Basically the temp sensor and 1k resistor act as a voltage divider.

Anyway I found several maps in the ecu rom.
But cant figure out which one is for the t-map sensor.
I can replicate each using 1k 1.5k or 2k resistors in series.
:crazy: :wtf:

The attachment shows 4 tables found in the ECU along with the t-map values using 1k, 1.5k and 2k resistors.

You mean: Air temperature sensor - linearisation T_air = f(U_ADC),
yes i located it but it is not used in my ECU, my stock MAP sensor does not have AIR temp sensor inside.

I should take a look at your bin closely to tell more about yours.

Oh yeah. I remember now. Your ECU uses the MAF sensor temp instead for control ?
Always found that peculiar :?

post7516#p7516 ...identified the temp sensor linearisation tables. :thumbup:
